D'Addario's premium uncoated acoustic string set that provides a crisp and clear sound to accentuate the unique tone of your guitar. NB1356 offer heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking. Nickel Bronze delivers unrivaled clarity, resonance and projection, as well as outstanding balance and harmonically rich overtones.

Featuring an innovative combination of nickel-plated phosphor bronze wrapped onto a high carbon NY steel core, these strings bring out the unique tonal characteristics of any guitar, allowing its natural voice to truly shine. Players will also enjoy improved tuning stability and higher break resistance, thanks to D’Addario-engineered NY Steel cores and plain steel strings.
